The host range and life cycle of Meloidoderita sp., found in Maryland and the first member of this genus reported outside of the Soviet Union, were studied. All known hosts of Meloidoderita sp. are in the Polygonaceae and none of those of M. kijanovae were parasitized. The time required to complete a life cycle from J2 toJ2 was 23 days at 31 °, and 28 days at 28° (day) and 22° (night). The unique transformation of the uterus into a sclerotized cystoid body containing eggs is discussed. Eggs within cystoid bodies could not be induced to hatch and the J2'S they contained were nonviable. Unlike the females, males develop outside plant roots; they were never associated with females or their egg sacs. Infection by nematodes of Meloidoderita sp. stimulates the formation of a definite altered cell complex in host plant roots. These transformed cells take the configuration of a slightly hypertrophied sheet of pericycle cells extending laterally and longitudinally from the nematode head which is always lodged in an endodermal cell.
